with grape-sugar, whereby the sticky or ad-4 hesive property ot' thegrape-sugar is largely neutralized and the grains or crystals of cane orbeet sugar are cemented together by the solidified grape-sugar..

My invention consists of the methods and 4apparatus which will behereinafter fully described, and pointed out in the claims.

The accompan yin gdrawin g represents 'a sectional elevation of auapparatus which may be employed in carrying out my invention.

y Arepresents a mixing apparatus which is charged with liquidgrape-sugar of the proper ldensity to cause its soliditication when leftundisturbed, and in which lthe liquid grapesugar is agitated and mixedwith cane-sugar or beet-sugar. If the liquid grape-sugar is notsufficiently cool, it is caused to circulate in the mixing-machine A incontact with a coolingsurface, whereby it is cooled oftand prepared forsolidilication. vThis mixing apparatus is preferably composed of a tankhaving a conical bottom, provided with one or more discharge-nozzles,which are controlled by suitable valves, and one or more coils ofpipe,through which cold-water is caused to circulate. An agitating-screw orother suitable agitator is arranged near the bottom ot the tank within acylinder open at the top and bottom, so that the rotation of theagitating-screw causes the Vliquid grape-sugar contained iu the-tankrto-flow upward through the inner cylinder and outward over the upper endthereof,thence downward along the cooling-coils and inward into theinner cylinder at its lower end, whereby the material contained in thetank is kept in circulation. B represents a bin or receptacle containingcane-sugar or beet-sugar in a granulated, pillverized, or otherwise moreor less iuelyre- `duced condition. This bin is provided with adischarge-spout, through which a certain portion of its contents can bedischarged into the mixing-vessel A. The cane-sugar or beetsu gar ispreferably mixed with grape-sugar in equal quantities, or thereabout;but any other suitable proportion ot' the ingredients may be employedaccording to the use for which the sugar is intended and the demandsVot' the trade. Any of the well-known grades of cane or beet sugarsuchas granulated,p|owdered, or brown sugar-may be used for this purpose.

The cane or beet sugar is preferably introduced into the liquidgrape-sugar by sprinkling the cane or beet sugar over the surface of theliquid grape-sugar by means of a shakingsieve, C, as represented iu thedrawing, or by any other suitable mechanism. The cane or beet sugar andgrape-sugar are thoroughly mixed in the vessel A by the operation of thestirring or circulating mechanism, whereby the cane or beet sugar andthe grape-sugar are thoroughly incorporated each with the other.

When the mixture has assumed the consistency ot' thick cream it is drawnlfrom the mixing-vessel A, through the discharge spout or spouts athereof, into pans or molds d, which latter may be temporarily placed,when lled, upon tables or supports D. These molds are preferably madeabout twelve inches wide, four inches deep, and thirty-six inches long;

but other suitable dimensions may he adopt-- ed, it being understoodthat the sugar will become hard and dry more quickly in small molds thanin large molds. The filled molds are then placed in a chamber, E, in orthrough which air is caused to circulate by a suctionfan, F, or anyother suitable device or mechanism, and whereby the sugarcontained'inthe molds is rapidly deprived of its heat and moisture. Air may beadmitted into the chamber E through openings or registersf at or nearits bottom, or in ,any other suitable manner. When the sugar in themolds has become slitticiently hard and solid it is preferably taken outof themolds and placed in the chamber E in such manner that a freecirculation of air is obtained between the slabs or bars of sugar,whereby the process of hardening and drying is rapidly completed. Thecompound so produced consists ofa hard and dry mass in which the grainsor crystals of cane or beet sugar are rml'y cemented or united togetherby the so'l lidied grape-sugar. p

If desired, the sugar may be delivered from the mixing apparatus Adirectly into barrels or packages,in which it becomes hard and solid,and in which it is placed upon the market.

. The slabs, blocks,` or bars of sugar may be sold without furthertreatment, or they may be ground in the following manner: The slabs arefirst taken to a cutting, scraping, or shaving machine, G, by which theslabs are comminuted or reduced to fine shavings. A-machine very welladapted for this purpose consists of a revolving cutter-head providedwith a suitable number of knives, g, against which the slabs of sugararefed by an automatic feedscrew, g. The cutter-head is surrounded by atight casing, g2, in which the comminuted material is collected and fromwhich it is discharged through a spout, g3, into a receptacle, H. Thecomminuted material passes from the receptacle H through a spout, h,into a mill, I, which may either be a disintegrating or a grinding orcrushing mill of any suitable or wellknown construction, and whereby thegrape-sugar is further reduced to the desired degree of Iineness.

The ground, crushed', or disintegrated sugar passes from the mill I to aseparating-machine, J, which consists preferably of aflat vibratingsieve, properly constructed to separate the coarse particles, which havenot been reduced to the proper degree of fmeness from the fineparticles, the latter falling through the meshes of the sieve intoareceiving-hopper, K, below, while the coarse particles pass over thetail of the sieve into a receptacle, L. A revolving bolt or any othersuitable separating-machine may, however, be employed, if preferred.

The coarse material collected in thel receptacle L is returned by 'anelevator, L', or suitable machinery to the mill I, in which it isreground, or to a separate mill, in which it is reground and from whichthe reground material is delivered to the separator. The sugar may besold in this comminuted condition, or it may .be mixed with anadditional quantity of granulated or pulverized cane or beet sugar inthe following manner:

M represents a mixing-machine of any suit' able construction. I preferto employ for this purpose a disintegrating-machine consistingessentially of several circular rows of pins or beaters revolving inopposite directionsv in a suitable case, which is provided with afeedopening near the center of the lnachine and with a discharge-openingat its circumference.

N represents a hopper or receptacle, which contains granulated orpulverized cane-sugar or beet-sugar, and which is provided with adischarge-spout, a, controlled by a slide, n', and leading to thefeed-hopperm of the disintegratingmachine. The hopper K, which re- Yceives the tine material passing through the meshes of theseparating-machine J, is also provided with a discharge-spout, k,leading to the feed-hopper'm of the disintegrating-mill, and controlledby a slide, la. W

The material contained respectively in the hoppers K andN issimultaneously discharged therefrom in two streams, which meet in thefeed-hopper m of the disintegrating-mill M, and pass together into thelatter, in which both materials are thoroughly mixed andfrom which themixture is Vdischarged in a continuous stream as a uniform product. Thematerial may be delivered directly into barrels or packages as it comesfrom the mixing-machine; or, if preferred, it may be delivered into astore hopper or bin, O, and drawn off into barrels or packages from suchhopper or bin. The supply of material tothe mixing-machine from thehoppers K and N is preferably so regulated that equal parts of bothmaterials are at all times supplied to the mixingmachine. When soregulated the ultimate product contains one part of grape-sugar to everythree parts of cane-sugar or beetsugar. These proportions may of coursebe varied to suit the demands of the trade. Any other `suitable andwell-known mixing-machine may be em ployed in the place of thedisintegrating-mill M, if preferred. The disintegrating-mill M ispreferably rotated at a slow rate of speed, so as to operate merely as amixingmachine, thereby avoiding the grinding or further reduction of thegranulated or pulverizedv cane or beet'sugar supplied to thedisintegrator.

If the sugar is sufficiently hard and brittle, the scraping-machine isomitted and the sugar fed directly to the mill, and in that case theblocks or slabs of sugar are preferably coarsely broken or cut by asuitable crushing or cutting machine before feeding the same to themill.

If desired, a quantity of dry pulverized or scraped grape-sugar may bemixed with the liquid grape-sugar in the mixing-vessel A. In this case asecond bin,- B, is provided, which contains the pulverized grape-sugar,and from which the dry grape-sugar is supplied to the mixing-vessel A,preferably in the proportion of one part of dry grape-sugar to ten partsof the liquid grape-sugar. The dry grape-sugar is preferably deliveredinto the mixing-vessel by distributing it in a spray over the surface ofthe liquid grape-sugar by means of a shak-- ing-sieve or any othersuitable distributing device.v 4

The incorporation of dry cane or beet sugar with the grape-sugardestroys the gummy or adhesive property of the grape-sugar and rendersthe compound hard and dry. It greatly reduces the time required for thesolidification of the sugar, and it lessens the tendency of the grape-sugar to absorb moisture from the atmosphereand ferment or' turn sour inwarm weather, thereby permitting the manufacture of the product to becarried on with the same success in warm weather as in cold weather.
